Gtx960 vs Gtx950

[GG_478]

Scared that PSU wont be able to handle gtx960 as it says "This PSU works great with systems running no more than one hard drive and video card GTX950 or lower" happy to get GTX950 as very similar results, what are peoples thoughts.

PSU: Coodmax 750 Watt PSU

Thanks

750W is definitely enough for any single GPU system, but I have never heard about this brand Coodmax therefore i'm not sure is that a solid part.
At this moment, I'd recommend GTX 950 or wait for new generation mid-low range card.

That's an offbrand unit that doesn't seem to have a lot published about it.
Do you already own this PSU? If so, could you post the load table? A 750W PSU should be able to handle a lot more than a 950 unless there's something weird about the way that power is being delivered to the actual components.

An example load table for a 750W psu:

If you don't already own the PSU, maybe look for a unit from a reputable manufacturer with published specs and a review from a major review site. Tom's Hardware PSU tier list is a good place to start.
If you pick a tier 3 or higher psu, you can use the following methods to determine what wattage you'll need. nVidia publishes a minimum recommended sytem power for their GPUs, as long as you're over that you should be fine in most cases. Alternatively, use something like pcpartpicker.com to figure out the total wattage needed for your system, multiply that number by 1.5 and you have your PSU spec.

Yeah it came with the case,
This is what is on the psu, i now think that it is 240watt but not sure your help would be appreciated.

That's definitely not a 750W PSU, that's closer to a 270W PSU, and that's only if the label is 100% accurate. I wouldn't even try to run a GTX 950 on anything under 300W PSU. NVidia's spec says 350W minimum system power.

Now, I don't know what the rest of your system is, but odds are, all the other components will proabably draw 80-100W, leaving 150ish for the GPU. That's ignoring the spike that happens when you turn the system on, an offbrand PSU would either just shut itself off due to over current protection or burn out if it doesn't have any OCP. You could try a 75W version of the 950, but I have my doubts it'll work. I'd be prepared to return the card. http://outervision.com/power-supply-calculator might give you more insight into what'll work, and what won't. I still recommend including a buffer over what the calc puts out (mostly because I don't trust the label on that PSU).

However, you could get an inexpensive PSU like like this EVGA 600B for 40USD that will work fine. This 600W PSU will actually give you your 600W and could push more than just a 960. It's unlikely that PSU standards change, so if you get a high quality PSU, it will last through several pc upgrades. For more reference on PSU's relative quality, check out the PSU Tier List
